| In an apparatus having a saturable magnetic core, a control winding wound on the magnetic core and supplied with a D.C. voltage in accordance with a desired phase angle, and an output winding wound on the magnetic core and supplied with an A.C. voltage through a load resistor, whereby the firing phase of a thyristor is controlled by a voltage across the load resistor, an additional winding is wound on the saturable magnetic core to detect the saturation of the saturable magnetic core by a rapid drop of a voltage across the additional winding. When the saturation is detected, the magnitude of the A.C. voltage applied to the output winding is increased. The phase angle characteristic of the magnetic phase shifter is determined under a low voltage condition prior to the saturation of the magnetic core, and after the saturation a high voltage is applied to the load resistor. | ||||||
